Abstract

Over the past 20 years, there have been many studies looking at how highlight disparity affects an observer's perception of glossiness. Most of these studies have used relatively smooth surfaces, and simple lighting models. We are using surfaces which are rougher and more naturalistic than those used before, using a rendering method which takes into account physically accurate properties of light to create stimuli which are as close to 'real' samples as we can currently generate. To this end, we present the results of a pilot experiment designed to look into this problem. These results seem to imply that the relationship between gloss perception, highlight disparity and roughness is more complex than previously reported.
